Answer:
2187/64
Step-by-step explanation:
first term (a) = 2
common ratio (r) = 3/2
8th term (t8) = ?
We know
Tn = ar^ n - 1
t8 = 2 * (3/2)^ 8 - 1
= 2 * 2187/128
= 2187/64
Answer: 3 <em>7</em>/14 + 2 <em>12</em>/14 = 5 <em>19</em>/14
Step-by-step explanation:
Find the LCM of the denominator.
2 = 2, 4, 6, 8, 10, 12, 14, 16, 18, 20
7 = 7, 14, 21, 28, 35
3 1/2 = 3 7/14
2 6/7 = 2 12/14
<em>3 7/14 + 2 12/14 = 5 19/14</em>
